IBM 3670 Brokerage Communication System - need old 1971 manuals

by jimkeo＠multi-platforms.com

Can anyone suggest where I might obtain an original or copy (they are less than 50 pages) of 2 IBM manuals: GA27-3048 IBM 3670 Brokerage Communication System Concepts & Configurator GA27-3049 IBM 3670 Brokerage Communication System Installation & Planning Also, if anyone recollects working with such a system (Merrill Lynch in early 70's?) I would appreciate a description of how a broker or analyst could specify stocks in which he/she was interested along with some price limits or ranges and then receive a message alert on the terminal if limits were exceeded during real-time monitoring of trades in that security. In other words how were price alerts implemented. Email me directly via jimkeo(a)multi-platforms.com with Subject "IBM 3670" if you can. Thanks! - Jim Jim Keohane, Multi-Platforms, Inc.

Looking for both parties who claimed my NeXT inkjet and IBM parts

by jingber＠ix.netcom.com

I had a rather lousy turn of events last night and hosed my inbox. I'm looking for the parties who negotiated a deal with myself for 1) NeXT inkjet printer, and 2) The remainder of the NeXT and IBM items. Thank You, Jeff

Well, that's a fair amount of progress, even without the keyboard.

With the "US BASIC" ROM removed it asked "What Language?". > Of course since the keyboard wasn't working I couldn't tell it anything. You wouldn't have been able to anyway. Without a language ROM of some sort, it won't listen to you. unless you have a Second Processor unit installed, and it drops to the "*" prompt. > With both the "US BASIC" and "DNFS" ROM removed it reported "View A2.1", > "No Text", Editing No File", "Screen Mode 7", "Printer Default" and a > "=>" prompt. Looks like I fell into some kind of monitor program. > Still can't do anything due to faulty keyboard. That's not a monitor prompt, it's the command mode of VIEW, which is a word processor. This is slightly odd. View is, in Acorn OS terms, a language, equivalent to BASIC, COMAL, LOGO, FORTH, Wordwise, or any number of terminal emulator ROMs. So removing BASIC but leaving View and the DNFS should have resulted in your getting the View prompt, just as it did when you took out both BASIC and DNFS. > I cleaned up before Christmas and misplaced the bag with the screws > for it, *&^(&%%! That's all right. No proper BBC Micro has screws, except three M3 machine screws to hold the PSU in place, and *possibly* some mushroom-head self-tappers to hold the PCB steady. The keyboard screws should be replaced with PCB clips for quick access, and the case screws should be thrown away ;-) -- Pete Peter Turnbull Network Manager University of York

BBC Acorn

Yes, I'm sure it is, I was just pointing out that in the general case, amount of memory is not a good way to tell. AFAIK, Acorn sold only Model Bs in the States. > It's not running at the moment but when it was it said soemthing like: > > "Acron version 2.1 > DFS OS > BASIC OS" > > There's also a EPROM that says "DFS OS" in it so I think it's supposed to say that. I've not seen a US model start up, but I expect Acorn removed the "BBC Microcomputer" part for trademark reasons (in many countries outside the UK, BBC is a trademark of Brown Boveri & Cie, and anyway it wouldn't mean the same in the States). Presumably they changed the other strings too. How many (EP)ROMs are in it? Do they have any numbers on them? > OK thanks for the pointers. I searched the net but found so many sites that I haven't had time to go throught them all. If you're looking for repair information, the ones I listed are good places to start. You might also consider joining the BBC mailing list. If you want to, send a message with "subscribe bbc-micro" in the body, to majordomo at cloud9.co.uk. > Nope, that's not what I got. It didn't say anything about BBC or Microcomputer or the amount of memory and it definitely said "OS" twice. I did get the beep then the speaker had a slight buzzing in it. (Possible due the the failing capacitor in the PSU). I was in the process of checking the PSU outputs for noise when the cap blew. It was quite noticeable! Maybe they changed the banners more than I thought. > Actually I didn't get a cursor. I wasn't sure if it was supposed to have one or not. Yes, you should. > Thanks for the description. That's about what I expected. Sounds like I need to find a VIA. I need one for my spares anyway. There are two mylar(?) ribbon cables that connect the keyboard to the main circuit board. Is the wide one the column inputs and the narrow one the row outputs? (Keeping my fingers crossed that it's that simple!) I doubt if it's that simple. UK models don't use mylar ribbons, they use a single 17-way notched IDT cable with a 0.1" pitch, and with a single-row Molex IDT header at each end. If the cable is damaged you can use ordinary 34-way cable with 34-way 2-row IDC headers; just ignore the second row. Download the service manual; it has the keyboard diagram, with pinouts. Fix the PSU first, obviously. The Beeb is a bit choosy about power regulation, and if the 5V and 0V connectors (of which there are three pairs) don't all make good connections to the board, you can get strange faults because the voltage may be too low at some points on the board. The red and black wires are +5V and 0V respectively. There's a purple wire for -5V, but this is only used for the serial port and audio amp. There's a +12V output but only on the AMP connector at the front, as it's only needed for peripherals. -- Pete Peter Turnbull Network Manager University of York
